Update from 17 June, 5:30 pm AEST: coal and gas are currently producing 78% of Australia’s electricity supply.

We need more renewables, obviously. Look at the contribution to Australia’s energy supply over the last 48 hours. After decades of subsidies to promote windmills, solar panels, hydro schemes and biofuels, the total output of renewable sources is woefully tiny. Not enough subsidies, I expect.
